Green Electronic Relay Board

A close-up view of a green electronic circuit board populated with four black relays, various screw terminals for connections, and an Ethernet port module (specifically a Lantronix XPort Pro). The board also features other electronic components, suggesting its function as a networked relay control module suitable for automation, remote switching, or industrial control applications. The clean layout highlights the components clearly.
